drm/amd/display: Clear state after exiting fixed active VRR state

[ Upstream commit 6f8f76444baf405bacb0591d97549a71a9aaa1ac ]

[why]
Upon exiting a fixed active VRR state, the state isn't cleared. This
leads to the variable VRR range to be calculated incorrectly.

[how]
Set fixed active state to false when updating vrr params
